In Version 7.3.2 issue with Quotes totaling using the Grand total function. I attached a screen grab of the issue. The first 4 group names have no problems totaling, but the 5th and the grand total on the page have issues. It seems to be multiplying by $100. Does this happen in the newer versions? Or is it fixed in a patch?
